Go Ferm Yeast Rehydration Nutrient (75 g)

Go Ferm Yeast Rehydration Nutrient (75 g)


Go-Ferm® is certified organic by OMRI. It is a natural yeast rehydration nutrient con­taining a balance of micronutrients. It was developed to enhance kinetics and thereby potentially avoid problem fermentations. Suspend Go-Ferm in the rehydration wa­ter before adding the selected active dried yeast culture. The yeast soak up the valuable bio-available micronu­trients as they rehydrate. Infusing yeast with these es­sential nutrients arms them against ethanol toxicity and optimizes nutrient availability to the rehydrating yeast culture. The result is fermentations that finish stronger.

Rehydration with Go-Ferm is effective for helping the yeast survive the fermentation. If these micronutrients were added directly to the must, competitive microor­ganisms would use a significant amount of them and others would be chelated by polyphenols or inactivated by SO2. Using nutrients that contain ammonia salts dur­ing the rehydration phase can be toxic to the yeast.

To Use:

  1. Mix Go-Ferm in 20 times its weight in clean 43°C(110°F) water. For every 2.5g of Go-Ferm, use approximately 200 mL of water.
  2. Let the mixture cool to 40°C(104°F) then add the active dried yeast.
  3. Let stand for 20 minutes.
  4. Slowly (over 5 minutes) add equal amounts of must (juice) to be fermented to the yeast slurry. Watch the temperature difference. Do not allow more than 10°C(18°F) difference between the must (juice) and the yeast slurry. Atemperate as neces­sary.

Storage: Dated expiration. Store at 18°C(65°F).
